PAUL HENRY PAULSEN, OF STU'RGEON LAKE, MINNESOTA.

SIDE SUPPORTEB FOB SAWMILLS.

Specification of Letters Patent.

Patented Dec. 28, 1920.

Application filed July 13, 1918. Serial No. 244,749.

To all whom it may concern:

Be it known that 1, PAUL Hnxnr PAUL- SEN, a citizen of the UnitedStates, residing at Sturgeon Lake, in the county of Pine and State ofMinnesota, have invented certain new and useful Improvements in SideSupporters for Sawmills; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in side supporters for sawingmachines, and has for one of its objects the provision of means forpreventing side swinging of logs or boards while being sawed, and whichobviates the necessity of dogging down the tail end of the log or boardwhen sawing the last plank to a one inch board.

Another object of this invention is the provision of means whereby theside sup porter can be conveniently controlled manually, and which iscapable of adjustment at the will of the operator.

A further object of this invention is the provision of a side supporterof the above stated character, which will be simple, durable andeflicient, and which may be manufactured and sold at a comparatively lowcost.

.Vith these and other objects in view, as will become more apparent asthe description proceeds, the invention consists in certain novelfeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described and claimed.

For a complete understanding of my invention, reference will be had tothe following description and accompanying drawing, in which:

Figure 1 is a plan view of a side supporter for sawing machinesconstructedin accordance with my invention,

Fig. 2 is a fragmentary vertical sectional view of the same,

3 is a fragmentary longitudinal sectional view of a supporter, and

Fig. f is a detail sectional view of means for holding a wheel to atrack.

Referring in detail to the drawing, the numeral 1 indicates the frame ofa sawing machine having mounted thereon the usual rotary saw 2. Theframe 1 has mounted thereon and associated with the saw 2 areciprocating carriage 3, provided with head blocks 4 and clamps 5. Theaforedescribed construction relates to a well known sawing machine towhich may invention is applied.

A vertical shaft 6 is secured to the frame 1 at one end thereof, and hassecured thereto a wing or board -7 by strap hinges 8. The free end ofthe wing or board is disposed ad acent the saw 2 upon one side thereof,or upon an opposite side of the saw from the carriage 3, and consists oftelescopic sections held against relative movement by means of a setscrew 9, providing means whereby the wing or board can be lengthened orshortened as desired by the operator. An adjustable rod 10 is pivoted tothe wing or board 7, as illustrated at 11, and carries at its free end ahorizontally disposed guide wheel or roller 12. The roller 12 is adaptedto travel upon one side face of a track 13. The track 13 is preferablyconstructed of T- shaped iron, which has its ends extended at rightangles to form supporting feet or legs 14, which are bolted or otherwisesecured to the ends of the frame 1. The wheel or roller 12 is of thegroove type to receive the stem or leg portion of the T-shaped iron ortrack, and which is disposed horizontally so that the wheel or roller 12can readily ride thereon. Arms 17 are connected to the axle of the wheelor roller 12 and carry at their free ends rollers 16, which engage theouter face of the track 13 for retaining the roller or wheel thereon.The rod 10 is capable of adjustment by being constructed of telescopicsections, so that the swing of the wing or board can be varied asdesired.

A rod 17 is connected to the axle of the roller or wheel 12 and isadjustably con nected to a controlling lever 18. The controlling lever18 is pivotally mounted to the frame 1 and by rocking said lever uponits pivot, the wing or board 7 can be moved to and from the saw 2.

In operation, a log is placed upon the carriage 3 and is fed upwardly tothe saw in the usual manner, whereby upon reciprocation of the carriagethe saw will cut planks or boards therefrom. The log is usually securedto the head block by the clamp 5, but when the machine is equipped withmy invention, the necessity of securing the logs is entirely obviated,as the free end of the board or wing can be swung against the log totightly hold the same against the head block.

While I have shown and described the preferred embodiment of myinvention, it

will be understood that minor changes in construction, combination andarrangement of parts may be made without" departing from the spirit andscope of the invention as claimed.

Having thus described my invention, what I claim is: i

A device of the character set forth comprising an adjustable wingpivoted at one of its ends to a saw frame, a track arranged adjacent thewing, a roller mounted on said track, a rod connected to said roller andto the free end of the wing, a second rod conthe opposite si e of thesaw from that on which thework lies. v

' In'testimony whereof I aflix my signature 20 in presence oftWowltnesses.
